"Lick me, M-chan. Come here." At first, I did whatever she said to make her like me. She sucked my toes, performed cunnilingus for a long time, and even inserted my penis... One day, I rebelled against her and she slapped me... At that moment, my penis was erect. "You really have a dirty penis. It's trembling." Every time she insulted me or ordered me around, my penis became excited. I decided. "I'm going to live my life as her licking dog."
